Chemical Structure
Description
The occurrence of Ethyl (S)-2-hydroxy-2-(4-iodophenyl)acetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl (S)-2-hydroxy-2-(4-iodophenyl)acetate (CAS 1579992-43-0), molecular formula C10H11IO3 and molecular weight 306.10 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl (S)-2-hydroxy-2-(4-iodophenyl)acetate (C10H11IO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 306.10 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Ethyl (S)-2-hydroxy-2-(4-iodophenyl)acetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
